In the Linux kernel, the following vulnerability has been resolved:
net: fix crash when config small gsomaxsize/gsoipv4max_size
Config a small gsomaxsize/gsoipv4maxsize will lead to an underflow in skdstgsomaxsize(), which may trigger a BUGON crash, because sk->skgsomaxsize would be much bigger than device limits. Call Trace: tcpwritexmit tsosegs = tcpinittsosegs(skb, mssnow); tcpsetskbtsosegs tcpskbpcountset // skb->len = 524288, mssnow = 8 // u16 tsosegs = 524288/8 = 65535 -> 0 tsosegs = DIVROUNDUP(skb->len, mssnow) BUGON(!tsosegs) Add check for the minimum value of gsomaxsize and gsoipv4maxsize.
